The built-in defaults in current versions appear to be:
blacklist {
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st|dcssblk)[0-9]"
devnode "^(td|hd|vd)[a-z]"
devnode "^cciss!c[0-9]d[0-9]*"
...
}
Note that this doesn't match xvd*, but is this still a thing with
current Xen versions, or has everything moved to vd* anyway?
